iMPRovEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.

To all .whom fit muy concern Be it known that we, Kanyon' Cox and Innononn COX, of the city of New York, in the county and State of N ew York, have inventedl new and uscful Improvements in Water-Wheels; and we do hereby declare that the following is a full, clear, vand exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing tbl-ming part. of this specification.

This invention relates to improvements in waterwhecls of that class in which the hydrostatic pressure of the water is obtained by passing it through a .circular case, in which the buckets or pistons fit closely between the induction and exhaust-ports on one side, and a eut-oit' device is used on the other side to prevent the back action ofthe water, and which are applicable for use as water-meters, rotary steam-engines, pumps, or blowers.

rlhe Vinwention consists in the combination, with radial buckets or pistons rigidly attached to the hub ot' the driving-shaft, of a drum or ring made in sections of rings, (preferably many as there are pistons or buckets,) and fitted in grooves or guides atthe ends ot' the case, eccentric to the piston-hub, which sections lap cach other at the ends, and cach has a hole at or about -the center, through which a bucket extends, the whole revolving with the buckets and shifting on cach other atthe lappingr ends, as required by the constant changes of the buckets, into the rim, due to the eccentric arrangement of the one to the other, and closing thc space at one side at' the wheel against the passage otthe water.

liigurel is a transverse section of our improved wheel;

Figure .2 is a section lwrpcndicular to the axis of the same; and

Figure 3 is asimilar section, divested ot' the rim of the ase, and showing a modification ol' the construction of the sectional ri-nn.

Similar letters ot' reference indicate corresponding parts. v

A is a circular case, having a longitudinal induetion-chute, 1;, at one side et' the axis, and a discharge-opening, C, at the other or thcrealmut, as may be preferred.

is the shaft; arranged iu the axis oi' the case, and carrying the radial pistons or buckets E, projecting from a solid hub attached toit, and litting the ends and rim ot' the ease closely between the supply Vand discharge-ports.

1I is a ring ot' nictal, made in as many sections li as there are buckets, of which there may be two or .moi-e, wider than the space between the ends ot' the case, and litted in a groove, I, in cach, which grooves are arranged eccentric to the axis ofthe ease, and so that they extend to the inner wall of the rim of the case, between chute B and discharge C, on the vary in consequence of the sections being moved out and in on the buckets bythe eccentric grooves, around which the ring is carried by the buckets.

The said sections are adjusted, as to length, so that -the ends will lap sufficiently to accomplish the object for which .they are intended, when most extended, as indicated at L, where they are at the greatest distance from the axis of the wheel, and yet not lap so much on the opposite side as to interfere with the buckets, it' arranged as in iig. 1, or with the shoulders )l et' each other, if arranged as represented in fig. 2, either ot' which arrangements we propose to make use of, or any other which will accomplish the same purpose.

The difference in the arrangements here shown consists iu makingthe .section in one ease half ou a greater and the other halt' ou a lesser radius, so that one-half laps the halt' ot' the next section on the outside, and the other halt' laps its fellow section ou the inner side; and in thel other case cach alternate section is wholly formed on the greater radius, and the other on the lesser. f

It is notniaterial which of these arrangements are used, or others equally as useful may be employed.

lhc holes through the sections have oblique walls, forming narrow bearings against the sides ofthe pistons'to admit of the vibrations necessary, owing t'o the eccentric arrangement of the one with the other.

It is believed that thisarrangement will work with much less friction than those wherein the pistons are made to slide in the hub, and the latter is arranged eccentrically to the case, while the buckets sustain the pressure oi' the water, or others of that character, for in this case, there being no objection to the space v within the ring being tilted with water, the pressure on the ring will be equal on both sides, and thc frictiomothcr than that of'the pistons on the sides and rim of the case, will be limited to that of the rings turning in the grooves and the working of the pistons through the holes ot' the rings, which will manifestly be but little in either case.

.Having thus described our invention,

Wcclainias new and desire to secure by Letters lateut- 'lhe combination, with the wheel-case and the buck cts or pistons, of a'scctional ring arranged eccentricaily to the axis ot' said case and buckets, substantially as specified.
